宁夏蝗虫地理分布格局的聚类分析

根据宁夏的自然环境和行政区划将宁夏分为22个分布区域。为方便聚类分析,根据分布范围将宁夏蝗虫分为全布种(22个区域有分布)、多布种(2～21区域有分布)和独布种(只分布在1个区域)3类。在以分布区域为特征做聚类分析的基础上,把多布种分组并确定重叠的分布格局,共分为14个组。各组蝗虫在宁夏的自然分布作为其分布格局。结果表明：宁夏蝗虫的多布种多呈不连续分布;分布格局与国内外基本相似;贺兰山是宁夏蝗虫分布的热点。不连续的环境是造成宁夏蝗虫多布种不连续分布的主要原因。     

青海省蚱属一新种记述(直翅目,蚱科)

记述采自青海省蚱属1新种,即黑胫蚱Tetrix nigrotibialis sp.nov.。新种近似于二斑蚱Tetrix bipunctata(Linnaeus)及拟二斑蚱Tetrixparabi punctata Zheng,其与上述2种的主要区别:1)前胸背板前缘平直;2)触角长于前足股节长的1.3倍;3)侧面观前胸背板上缘弧形隆起,中部平直;4)肩部之间不具1对短纵隆线;5)前胸背板后突到达后足股节顶端;6)后足股节下侧及后足胫节黑色。模式标本保存于陕西师范大学动物研究所昆虫标本室(正模)及青海师范大学生命与地理科学学院(副模)。     

中国蝗总科昆虫科间系统发育关系支序分析：直翅目;蝗亚目

在形态学研究的基础上,配方选择了１２个特征,利用Ｈｅｎｎｉｇ８６程序包,以支序分析探讨了中国蝗总科昆虫科间的系统发育关系。结果表明蝗虫类昆虫稳定的分为两大类,即癞蝗类和蝗类,本文建议蝗虫类昆虫分为分为两个总科较宜。长腹蝗亚科似归入斑腿蝗亚科更为合理;而皱腹亚科则应提升为独立科。     

蟋蟀精子表面LCA及ConA结合糖复合物的分布变化

LCA and ConA-binding glycoconjugates on cricket (Teleogryllus emma) sperm surface were detected with fluorescence microscope after FITC labelling for better understanding of the distribution of glycoconjugates during spermatogenesis and spermiogenesis. FITC-LCA and FITC-ConA were bound on the spermatocytes, and their distribution changes in the process of spermiogenesis were observed .In the testis sperm, FITC-LCA and FITC-ConA were mainly bound on the head and neck region. That is different from the mark pattern of spermatophore sperm, in which the nucleus, neck region and front of the tail showed obvious fluorescence mark, especially the acrosome complex and neck region exhibited stronger mark. The mark patterns of FITC-LCA and FITC-ConA were similar,though the former was distinctly clearer than the latter. But a little difference still exists in both of them. For example in the ninth stage of spermatid, FITC-LCA mark is located on the spermatid head and neck region, and FITC-ConA mark on the spermatid head, neck and front of the tail region. When fixed germ cells were treated with PBS instead of lectin solution, or fixed cells were incubated with lectin solution, which have been treated with 0.1 mol/L specific sugar inhibitor, i.e.α-D-mannose for FITC-LCA and FITC-ConA, and α-D-glucose for FITC-ConA, no mark was observed on the cells. Those results indicate that FITC-LCA conjugated glycoconjugates has the α-D- mannose residue, and FITC-ConA conjugated glycoconjugates has the α-D-mannose and α-D-glucose residue. The investigations show that the changes in glycoconjugates distribution of cricket sperm is similar to those of other insects and mammals. The evidence exhibit that a common rule of the glycoconjugates distribution on the sperm surface is followed by most of animal sperm which may relate to the function of sperm physiology.
